The image above is of a common water plant, 1. Water Mint-(Mentha aquatica) was taken a few months ago with the intention of following the progress through the summer season.
Description Water Mint is a perennial plant growing to nearly a metre in height when competing with tall vegetation, but more often no more than 20 to 30cm tall. The stems of this and other mint species are square-sectioned; they can be either green or purple, as also are the oval leaves. another variable feature of Water Mint is the degree of hairiness of its leaves and stems, which on occasion are almost hairless. Typically 4 x 2.5cm the leaves are opposite and finely toothed. The flowers of Mentha aquatica are very small and form crowded near-spherical inflorescences. Each of the pinkish-purple flowers has a four-lobed corolla some 3-4mm long, and four protruding stamens. Below each whorl of flowers are a pair of opposite leaves. In suitable habitats Water Mint spreads rapidly by means of its rooting rhizomes.
